OREAiVlING-CAN.

SPECIFICATION forming part of Letters Patent No. 356,511, dated January25, 1887.

Application filed March 15, 1886. Serial No. 195,239. No model.)

To all whom it may concern:

Be it known that 1, JOHN TURNER, a citi zen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Creaming-Cans, of which thefollowing is a specification.

My invention relates to cans for setting milk for cream which areprovided with automatic devices for separating the milk from the creamby withdrawing the former from the bottom of the can and leaving thecream therein, by means of an adjustable faucet or draw-off nozzle.These cans are ordinarily provided with a transparent window having agraduated scale to indicate the thickness of the cream in the can. Thedraw-off nozzle, which communicates with the bottom of the can, is thenadj usted in height to the thickness of the cream, whatever that may be,so that the faucet may be set by the attendant and the milk left runningwithout further attention. The draw-off nozzle which is now commonly inuse, and which for many obvious reasons is the best, simplest, andcheapest adjustable draw-off nozzle for the purpose, consists simply ina rotary valve carrying a tube of the requisite length, the curved mouthof which tube may be adjusted at different heights, or the valveentirely closed by simply swinging or turning the same into differentpositions. Great difficulty, however, has been experienced in thepractical use of these rotaryadjustable nozzletubes in setting or fixingthe mouth of the nozzle at the required height to correspond to thedepth of the cream. Owing to the curved or cylindrical surface of thecan,an ordinary graduated scale corresponding to the transparentcream-scale at the top of the can cannot be used, or if it is employedit is of very little service or assistance in adjusting the posit-ion ofthe rotary nozzle, especially at its lower positions. To overcome thisdifficulty in the use of these rotary adjustable nozzles in myinvention, which consists in the novel devices or combination of devicesherein shown and described,'and more particularly set forth in theclaim, I provide the can near the valve with a graduatedarc scale andthe swinging tubular arm of the valve with a pointer, so that the nozzlemay be set by this scaleat any desired height to correspond to the depthof the cream as indicated by the cream'scale at the top of the can. Thegraduation-marks upon this are scale correspond to the graduation marksupon the graduated cream-scale; but it will be observed that thegraduationmarks upon the arc scale are not equidistant apart, as thetube has to swing through different arcs to depress its mouth a unitdistance as it moves from near a vertical position to nearly ahorizontal.

In the accompanying drawings, which form a part of this specification,and in which simi; lar letters of reference indicate like parts, Figure1 is a side elevation of a Cooley creamercan provided with my invention,and Fig. 2 is a front view of the same. Fig. Sis a detail sectional viewof the nozzle.

In said drawings, A represents the can, which may be of the constructionshown or of any other suitable construction.

B is the transparent graduated cream-scale or window, having marks b, toindicate the depth of the cream in the can.

C is avalve communicating with the interior of the can near its bottom,consisting of ahol low stationary plug, C, having peripheral opening orport, and a rotary or revolving shell, C, fitted thereon. This rotaryshell part of the valve is provided with a tubular arm, D, in which fitsthe draw-off or nozzle tube E. The nozzle-tube E is furnished with acurved mouth or end, 0, to properly deflect or direct the stream flowingtherefrom when the nozzle-tube is turned in differentpositions. Thetubular arm D is provided with a pointer, d, and the can or the plugpart C of the valve, is furnished with a graduated-arc scale, F, havinggraduating-marksf, to indicate when the arm D and its tube E is swunginto position to bring the mouth '6 of the nozzle to heightscorresponding to the marks or graduations b on the cream scale 13. Thescale-plate F is preferably cast integral with the hollow plug part C ofthe valve, and is soldered directly to the can, and it thus at the sametime forms a flange or shoulder for the better and more secureattachment of the valve to the can. The draw-off nozzle or tube E may bemade integral with the arm D and shell parts C of the valve; but it ispreferable to make it detachable, as shown in the drawings, forconvenienoe in cleansing as well as manufacture and shipment. Thedistance between the graduating marks f varies, as the arm D must movethrough different arcs to elevate or depress the mouth of the nozzle ean equal distance at different parts of its travel. The variation in thedistance between the marks f is also somewhat due to the differentsiphoning effects of the curved end of the tube E in its differentpositionsas it swings from near the vertical to near thehorizontalposition.

The markf is used to indicate the vertical position of the valve part 0and scale-plateF in attaching the same to the can. The mark or stop findicates when the rotary shell G is swung back sufficiently to entirelyclose the valve.

I hereby expressly disclaim, as forming no part of my invention, thedevice shown and described in Letters Patent of the United States No.321,340, granted June 30, 1885, to I. G. Butler. In said Butler patentthe port is on one side of the plug or pivot on which the shell turns,and it extends horizontally through a flat vertical flange or collarsurrounding the pivot. In my invention the hollow plug serves both as apassage for the liquid and a pivot for the shell and swinging drawofftube.

I claim The combination, with can A, of creamscale B, stationary hollowplug part 0 of the valve, secured to said can and provided with arescale-plate F, cast integral therewith and having radial graduations,rotary shell part C of the valve, provided with tubular arm D, havingpointer (l, and detachable nozzle-tube E, having a downwardly-curvedmouth-piece, e, to deflect the stream and prevent drip, the graduationson said are scale indicating heights or positions of thedischarge-orifice of said mouth-piece corresponding to the graduationsin said scale 13, substantially as specified. I

JOHN TURNER.
